FOUNTAIN-PEN.

Specification of Letters Patent.

Application filed August 23, 1909.

To all whom it may concern:

Be it known that I, WILLIAM I. Fnnnis, a citizen of the United States,residing at Westfield, county of Union, State of New Jersey, haveinvented a new and useful Improvement in Fountain-Pens, of which thefollowing is a specification.

My invention relates to an improvement in fountain pens in which the inksupply is contained within an elastic sack or reservoir of soft rubber,or other suitable material, contained within a hollow casing of hardrubber, or other suitable material, and which reservoir is filled withink by the compression of the reservoir or sack and then immersing theopen end of the pen into an ink supply and allowing the elastic sack toexpand to its normal shape.

The objects of my invention are to provide improved means for compressinthe elastic sack when it is desired to refill the fountain pen and toafford improved means for aifording access to the compressing mechanismwhen required for use, and improved means for protecting same fromaccidental compression when not in use. I attain these objects by themechanism illustrated in the accompanying drawings, in which-- Figure 1is a view in elevation of a fountain pen embodying my device, closed forcarryln in the pocket; Fig. 2 is a horizontal sectiona view of my devicewith the compression mechanism exposed ready for use in compressing theelastic sack; Fig. 3 is a side view of the compressor bar used forcompressing the elastic sack; Fig. 4 is a top view of the compressingmechanism shown in Fig. 3.

Similar letters refer to similar parts throughout the several views.

A, represents the outer casing of hard rubher or other suitablematerial; B, the in closed elastic ink reservoir or sack of soft rubberor other suitable material; C, a slot, or finger-hole, cut in the outercasing, A, through which the finger or other convenient means, may beinserted to press against bowed projection, I, of the presser bar, D,which compresses the elastic sack; E, is a sleeve securely attached tothe holder A, and horizontally sliding thereon, for opening and closingthe slot G; F, is a spring attached to the presser bar D, the prongs G Gof which spring against the sldes of the interior of the casing, A, andhold the presser bar, D, in place in the casing A.

J, is the ink feeding device between the writing pen and the elastic inkreservoir.

K, is the conical surface of the outer casing at which the forward endof the sleeve E is held by means of a tight conical frictional joint.

The operation of my device is as follows: When it is desired to fill thefountain pen,

the sleeve, E, is moved toward the rear end of the casing, A, (as shownin Fig. 2) exposing the slot 0; the presser bar, D, is then depressed bythe insertion of the finger, or other suitable means, and the front, orpen end, of the fountain pen is dipped into an ink supply; the finger isthen removed from the presser bar and the elastic sack resumes itsnormal shape and is filled with ink, the ink being forced into theelastic sack by atmospheric pressure. The sleeve, E, is then movedforward toward the point of the pen where it is held firmly in place onthe casing, A, and covering the slot C, by means of a tight conicalfrictional joint.

The presser bar, D, has a flat bearing surface which bears on theelastic sack, B, for the entire length of the presser bar. At the pointwhere the presser bar, D, is exposed through the slot, C, it has abowed-outward projection I, thereby affording improved means for contactwith the finger when compressing the elastic sack. By means of the sprinprongs, G G, secured to the presser bar, D, by a toggle joint, J, thepresser bar, D, is securely held in place within the casing A, by theaction of the spring prongs, G Gr, springing against the interior sidesof the casing,

The pen is supplied with the usual cap, H, for protecting the writingpen when carried in the pocket; this cap may be placed upon the rear ofthe holder as shown by the dotted lines in Fig. 1 when the pen is inuse.

I claim:

In a fountain pen the combination of a writing pen, an inelastic casingor holder, an elastic ink reservoir within said casing,

an ink feeding device between the writing pen and said elasticreservoir, a presser bar within said inelastic casing but outside theelastic ink reservoir and secured within said casing by a springattached by a link to the pose and to cover said slot which sleeve 10When in position to cover said slot is securely held in place on saidouter casing by a tight conical frictional joint.
